## Highlights - Fixes a regression in service accounts/access keys for the root-user stopped working in the last release, a side-affect of a security bug-fix has been addressed. - Fixes for rename2() usage in decommission and rebalance on versioned buckets with objects having more than a version. this can lead to an inconsistent state() on the object requiring manual intervention. If you are planning to rebalance or decommission on a cluster you are advised to upgrade to this release - #18964 - Fixes for memory leaks observed in the new websockets implementations, causing a gradual build-up of memory in GiBs on busy clusters with heavy READ operations. - Optimizations for internode communication for variety of APIs ranging from IAM, Bucket Metadata. reducing internode connections to bare-minimum, there will be some more optimizations coming in this area for deploying MinIO at > 300 node clusters. ## What's Changed * move a collection of peer APIs to websockets by @harshavardhana in https://github.com/minio/minio/pull/18936 * Improve object reuse for grid messages by @klauspost in https://github.com/minio/minio/pull/18940 * batch: Fix a typo while validating smallerThan field by @vadmeste in https://github.com/minio/minio/pull/18942 * fix: `null` inline policy handling for access keys by @donatello in https://github.com/minio/minio/pull/18945 * log: Use error log type instead of Application/MinIO type by @vadmeste in https://github.com/minio/minio/pull/18930 * Fix some leftover issues from PR 18936 by @fwessels in https://github.com/minio/minio/pull/18946 * simplify deadlineWriter, re-use WithDeadline by @harshavardhana in https://github.com/minio/minio/pull/18948 * Fix ineffective recycling by @klauspost in https://github.com/minio/minio/pull/18952 * deprecate disk tokens, instead rely on deadlines and active monitoring by @harshavardhana in https://github.com/minio/minio/pull/18947 * move Make,Delete,Head,Heal bucket calls to websockets by @harshavardhana in https://github.com/minio/minio/pull/18951 * Fix mux client memory leak by @klauspost in https://github.com/minio/minio/pull/18956 * disconnected returns, an unexpected error to List() returning 500s by @harshavardhana in https://github.com/minio/minio/pull/18959 * xl: Disable rename2 in decommissioning/rebalance by @vadmeste in https://github.com/minio/minio/pull/18964 * Fix typo in api-router.go by @fwessels in https://github.com/minio/minio/pull/18955 * Add more advanced cases for dangling by @harshavardhana in https://github.com/minio/minio/pull/18968 **Full Changelog**: https://github.com/minio/minio/compare/RELEASE.2024-01-31T20-20-33Z...RELEASE.2024-02-04T22-36-13Z
